Nuestras plataformas lab-on-chip para la manipulación de partículas
SU-8 layer containig the channel over a substrate to perform the mass transfer and, with it, the particle or cell separation.
Particle collection at the center of the channel at 500KHz : ICU’07 Vienna, Biotech 2006
Applications of Ultrasounds for particle manipulation
Acoustic Agglomeration in Aerosols
Particles interact under acoustic waves giving rise to acoustic agglomeration at certain hydrodynamic-acoustic conditions.
Mechanisms governing the particle interactions induced by Ultrasounds can be analyzed observing the particles during the application of the acoustic field. The particle trajectories can be reconstructed from their bright traces filmed during their approaching processes subjected to horizontal standing waves:
